Investigating Risk Factors for Falls among Community-Dwelling Older Adults According to WHO's Risk Factor Model for...

Area of Science:

• Gerontology
• Public Health
• Epidemiology

Background:

• Falls are a major public health concern for older adults.
• The World Health Organization's Risk Factor Model for Falls provides a framework but lacks comprehensive single-model quantification.
• Previous studies have not holistically assessed fall risk factors within this model.

Purpose of the Study:

• To examine risk factors for falls among older adults using the Risk Factor Model for Falls.
• To quantify the association of various factors with falls in a single model.
• To identify key modifiable risk factors for targeted interventions.

Main Methods:

• Secondary data analysis of 10-year Minimum Data Set-Home Care records (2005-2014).
• Inclusion of 89,100 community-dwelling older adults aged 65+ in Hong Kong.
• Logistic regression analysis to identify significant fall risk factors, including meteorological data.

Main Results:

• 37 out of 70 analyzed factors were significantly associated with falls.
• Behavioral risk factors demonstrated higher odds ratios for falls compared to biological, socioeconomic, or environmental factors.
• Functional status, alcohol consumption, and outdoor locomotion were identified as having the largest odds ratios for falls.

Conclusions:

• Behavioral risk factors exert a significant, yet modifiable, influence on falls in older adults.
• Falls prevention strategies should prioritize interventions targeting behavioral risk factors.
• Addressing functional status, alcohol use, and outdoor mobility can enhance fall prevention efforts.
